SPECIFICATION forining part of Letters Patent No. 733,068, dated July 7,1903 i Application filed March 26, 1902. Serial No. 100,111. (No model.)

. JofAnderson, county of Madison, and State of Indiana, have invented acertain new and useful Pessary; and I do hereby declare that thefollowing is a full, clear, and exact description thereof, referencebeing had to the accompanying drawings, in which like numerals refer tolike parts.

The object of this invention is toimprove the construction andarrangement of pessaries, to render them more convenient and efficientinuse, and especially to enable them to hold the medicine andto impart itslowly and gradually.

The nature of said invention will be understood from the accompanyingdrawings, showing one form of said invention, and the followingdescription and claim.

In thedrawings, Figure 1 is an elevation of the pessar'y when not inuse. Fig. 2 is a plan view of the same. Fig. 3 is an elevation of thedevice when collapsed in use. Fig. 4 is a bottom view of the same whencollapsed. Fig. 5 is a central vertical section when not collapsed. Fig.6 is a central vertical section when collapsed.

In said drawings I show practically a vessel inade of rubber or likecollapsible and preferably resilient material. Said vessel iscylindrical, with the lower end open and with the central portion 10contracted and of slightly smaller diameter than the extreme lowerportion 11, while the upper portion 12 is enlarged and flaring, somewhatlike a funnel. The upper end 1.3 is closed and semispherical, with theconcave side upward and the convex side extending into the cylindricalportion of the vessel. The rim of the bowlshaped upper end is formedintoan endless tube 14:, that is air-tight and contains air. The function ofthe rim 14 is merely to distend the bowl-shaped upper end 13 of thevessel and hold it as nearly as possible while in use in the shape andposition it is shown in the drawings. I do not wish, therefore, to

limit the invention to a rim containing air;

but that is preferable. In manufacture the bowl-shaped end 13 and therim 14 are made together, while the remaining portion is together, andthen the two parts united in the position shown in Fig. 5.

The bowl-shaped end 13 is perforated centrally at 15, and within thevesselasponge 16, saturated with medicine,is placed against the convexside of the bowl-shaped end 13 and between it and the walls of thecylindrical portion of the vessel.

In use the cylindrical portion of the device is collapsible, thuscompressing the sponge 16 and forcing some of the medicine therefromthrough the perforation in the bowl-shaped end 13. To collapse thedevice, the end portion 11 is turned, thus twisting the central portion10 and causing it to be drawn tightly down upon the spindle. Theappearance when collapsed is shown in Figs. 3, 4, and 6. IVhen thuscollapsed, the medicine from the sponge cannot escape through the openend of the vessel.

The vessel is made of material that is impervious to fluids.

Instead of the sponge 16 any absorbent that will take up and impartfluid may be substituted.

What is claimed to be'the invention, and to be secured by LettersPatent, is-

A pessary comprising a cylindrical vessel made of resilient materialimpervious to fluid with one end closed and extending inward andperforated and the other end open to permit the ready introduction ofabsorbent material, and with a rim on the open end which by rotationwill cause the vessel to collapse both longitudinally and incross-section, substantially as shown and described.

In witness whereof I have hereunto affixed my signature in the presenceof the witnesses herein named.
